As of 1 January, 1997, MIR began using deferent set of 2 meter frequencies
than it had since 1 November 1996. On 1 November it began using 145.8 MHz
as both uplink and downlink for packet. For voice, 145.2 MHz was used for
the downlink and 145.8 MHz for the uplink. On 1 January the frequencies
became, 145.2 MHz for the uplink for both packet and voice and 145.8 MHz as
the downlink for both modes. Unfortunately an ANS released a bulletin on
29 December, which listed the old arrangement. We are sorry if confusion
was caused by this, but we were not informed beforehand of when the
impending change would take place. The correct frequencies are carried in
the Satellite Status bulletins which follow.
Some have questioned AMSAT-NA's possible role in the change which took
place
1 November. AMSAT-NA President Bill Tynan W3XO informed ANS that this
question had been taken up by the organization's Board of Directors when it
met in Tucson in mid-November. Frank Bauer, AMSAT-NA's Vice President for
Manned Space Programs, had informed the Board of MIR's frequency change
from 145.55 MHz to the 145.2/145.8 combination.. He said that this change
had been recommended at the IARU (International Radio Union) Region 1
meeting in Tel Aviv Israel in October. Region 1 is made of Europe and
Africa. Tynan expressed surprise that a recommendation, affecting the
entire World reached at a meeting involving only representatives of Region
1,
would be implemented without consultation with the other Regions. The
AMSAT- NA Board agreed with Tynan, and passed a resolution decrying the
change, involving as it did, 145.2 MHz. They noted that this a repeater
frequency in Region 2 (North and South America), and hence is not
suitable for any use involving space operation. Various members noted
that reports of interference had already been registered.

A0-13 FIRST AND LAST QSO's

BID: $ANS-012.02
Dave Guimont, WB6LLO, is compiling a list of stations who made QSO's
during the first and last few orbits of AO-13. Interest in the project has
come from a surprising number of sources. While accumulating data for the
first and last days of Oscar 13, Dave was immediately reminded of the fact
that it takes two orbits to cover the world. The callsigns in this list
are from opening day orbits #80, 22jul88, and #81, 23jul88. The final
orbits represent orbits #6479, 22nov96, and #6480, 23nov96. Graham,
VK5AGR,
turned off the transponders on 23nov96 on orbit #6480, MA 99; orbit #6480
continued on telemetry beacon only. This data was accumulated from various
sources.
Those with knowledge of the opening and final days of AO-13 transponder
operation, are asked to check both lists for errors and omissions. The
lists are arranged alpha-suffix order. It is requested that these
preliminary lists not be published until they can be verified. Information
about stations outside of the USA which made contact during these times is
particularly sought.
At first glance, there are only five stations that appear on both lists:
WD4FAB, WB6LLO, DB2OS, G3RUH and W6HDO (now K7RR). There are surely many
others. Other call sign changes may have taken place. Those active on AO-13
are asked to check their logs, and encourage acquaintances to do the same.
Please respond to wb6llo@amsat.org, or via conventional mail or telephone .
Those reporting are cautioned not to use orbit numbers that were logged,
other than from the satellite itself.. Instead, use UTC date for all
reference unless the orbit number was obtained from AO-13's telemetry.
NASA orbit numbers have been in error consistently, sometimes by as much
as two orbit numbers.

BID: $ANS-012.04
During the time period February 4th through 24th a second German/Russian
space mission is scheduled. German astronaut Dr. Reinhold Ewald , DL2MIR
together with his Russian colleagues will fly to the Russian space station
MIR. He will perform an extensive experimental program on board the space
station. Dr. Reinhold Ewald was already member of the substitute crew for
the MIR'92 mission during which Klaus Dieter Flade (DL1MIR) participated as
the first German astronaut attending the Russian spacestation MIR. During
this mission Hans Schlegel (DG1KIH) who was on board of the German/USA
Spacelab mission D-2 will act as substitute crew member. ANS is pleased to
learn that another "German Radio Amateur" is going to space and we wish him
and the entire crew all the best, and we hope for an overall successful
mission.
During this mission the SAFEX equipment(Space AmateurFunk EXperiment) will
be used primarily to inform interested ham radio operators on actual space
events. Due to the heavy workload of astronaut Reinhold the QSO mode has
secondary priority. Therefor Reinhold will use the digital voice recorder
of SAFEX to transmit automatically actual information about the mission.
The SAFEX equipment at the MIR space station is build by the German Hams
and operates in the 70 cm band and works in Packet Radio (Digi & Mailbox)
or
in Voice (QSO) mode (Repeater or Duplex).For detail information see The
AMSAT Journal" for Nov/Dec 1995.
A special QSL card will be distributed to operators with SAFEX, either for
a listening report of the digital voice recorder or a QSO via SAFEX
To prove the voice transmission or a radio connection via SAFEX the
operator
has to send his own QSL card including a computer WAV-File
on 3.5 disc of the voice recording. Both have to be mailed to DF0VR, Ham
Radio Group at DLR Oberpfaffenhofen, Postfach.1116, D-82230 Wessling.
ANS hopes for good reception of the voice recordings of Dr. Reinhold Ewald,
DL2MIR from the MIR space station and good connections via SAFEX (RR0DL).

The sat is giving extremely good downlink signals on 2 meters. In
this period of poor propagation on 15 m, the T-mode is providing very
easy access to the satellite. Interesting DX activity has been spotted
in Europe with stations in Egypt, Crete, Cameroon, etc.

It being listened to by stations in Germany, France, Spain, Canary Islands
(EA8), etc.
[ANS thanks Miguel A. Menendez, EA1BCU, for this report.]
As of NOV 2, the AO-27 schedule is as follows:
TEPR 4 = 16 = 8 Minutes in Length
TEPR 5 = 52 = 18 Minutes in Length
TX-3 is on Mid Power during TEPR 5.
This will have the TX turn on 8 Minutes after the satellite
enters the sun for a duration of 18 Minutes. This is a "back to US
Latitudes"operation.
N4USI, AO-27's current Command Station sends his thanks all for
their messages about the satellite turning on later than expected. He
reports he's deliberately letting the "turn on" time drift later
(for about 4-5 Minutes) so stations in the southern latitudes can also
have a chance to work AO-27. Every few months he will be letting the
turn on time drift like this to give more stations a chance to make
contacts thru the satellite.
[ANS thanks Michael, N4USI , AO-27 Control-op, for this

AO-10:
(Uplink 435.030-435.18MHz CW/LSB, Downlink 145.975-145.825MHz CW/USB)
Operating normally. Stacey E. (Chuck) Mills, W4SM, reports that
Ken Ernandes is attempting to obtain updated Keps, however the satellite is
apparently in an inopportune orbit to accomplish this. It has been
suggested that amateurs may be able to do better, at least for the next few
months by various ranging experiments of their own.. There have been
various discussion on AMSAT-BB on this. However, in the meantime, AO-10's
orbit doesn't change very fast. Parameters are now off by a bit,
especially at perigee. W4SM calculated the blon/blat, -125/5, about one
year ago and is waiting to see if predictions for this year hold up.
